5. OperationandMENUdescription

5.1 Checktheproductspecifications

Beforestartingtousethisproduct,checktheproductspecificationsthatcanbefoundinthismanual
orthebasicinformationlocatedonthebackpaneloftheproduct.
ThedetailedproducttechnicalspecificationscanbefoundinSection7.Foraspecificapplication,
thepressureratingmustnotbehigherthanthesystempressuretobemeasured,andtheflowrange
shouldalsobewithinthespecifiedones.Inmostcases,theuseofahighfull‐scalerangedmeterfor
theverylowflowratemeasurementoftenresultsinerroneousdata.Thegastobemeasuredmust
alsobeconsistentwiththatspecifiedbytheproduct.Beparticularlycautiousaboutthesupplied
voltageindicatedinthespecification.Ahighervoltagemayleadtoirrecoverabledamage,anda
lowervoltagewillnotpowertheproductforanydesiredfunctions.
Forthebestperformanceoftheproduct,itisadvisedthatthegastobemeasuredmustbecleanand
freeofparticlesorotherforeignmaterials.

5.2 Checktheleakage

Checkgasleakagebeforeanymeasurement.Ifitisneeded,thepressurizednitrogenoraircanbe
usedfortheleakagecheck.

5.3 Powerthemeteranddigitaldataconnection

AlthoughthisproductcomplieswiththeCE‐requiredEMCregulations,italsorequirestheproductto
beusedaccordingtothestandardelectricaldevicepractice.Forgeneral‐purposeusage,themeter
canbepoweredby4AAbatteries.Besuretoselectthebatterieswithsafetyproofandwithinthe
expirationdate.Donotusebatterieswithoutaknownmanufacturerandexpirationdate.Formodels
withcontrolvalvesorforextensiveusage,itisrecommendedtohavethemeterpoweredwith
externalDCpoweroranAC‐DCadapter.Makesurethesupplyvoltageiswithintherangeofthe
specifiedonesinSection7.Beforeconnectingtheproductwiththeexternalpower,makesurethe
standardelectricaldeviceprecautionssuchasEDS(electrostaticdischarge)andDCvoltageare
observed.Excessiveelectrostaticdischargemaydamagetheproduct.

ThepoweranddataareconnectedviaastandardType‐CUSBport.Themanufacturer‐supplied
Type‐CUSBcablehasthescrewlockingfixture.Itisrecommendedsuchafeaturetoensurethecable
isproperlyengagedandwillnotbeaccidentallygotunplugged.

connectedtothereceiverside.

5.4 Wirelessdatacommunication

Theproducthasoptionalwirelessdatatransmission,includingBluetoothLE4.2,LoRa,WIFI,andNB‐
IoTwirelessdata.
AnapplicationAPPnamed“SiargoSmartMeter2.0”canbedownloadedfromeitherAppleStorefor
smartdevicesbasedontheiOSsystemorfromGooglePlayStoreforsmartdevicesbasedonthe

TheAPPprovidesthebasicfunctionstoaccessthemeter/sensordata,plotaninstantflowratechart,
calculatetotalizedoraccumulatedflowvolumeataspecifictimedefinedbytheuser.Itallowsthe
usertosendthelocaldatainstantlytoaremotedestinationwhenthewiredconnectionisnotan
